California CDL Passenger Endorsement: Prohibited Practices Test 2026

Some rules for bus drivers are written as flat prohibitions, and the exam asks about them directly. This California CDL passenger prohibited practices test covers what you simply do not do behind the wheel of a commercial passenger vehicle in 2026.

No refueling with passengers on board in an enclosed space. No talking with riders or engaging in distracting activity while the bus is moving. No towing or pushing a disabled bus that has passengers aboard unless getting them off would be unsafe, and then only to the nearest safe spot. No hazardous materials in the passenger compartment. No standing forward of the standee line, and no baggage in the aisle or blocking an exit.

Behind each prohibition is a predictable failure the rule prevents, and the California Commercial Driver Handbook explains the reasoning. Learn the reason and you will not have to memorize the list. Check your California CDL Manual for the exact number of questions on the California passenger endorsement test.
